[Metastasis of a malignant melanoma simulating a primary mandibular sarcoma].
The rare case reported here was a mandibular metastasis of a malignant melanoma located in the nape of the neck and surgically removed. 4 years later, occurred a fibrosarcomatous mandibular tumour without local recurrence. The metastatic nature of this tumour was difficult to prove by means of immunohistochemical and ultrastructural methods. This case illustrated the eventuality of a desmoplastic change in metastasis of a common malignant melanoma. The histogenesis of this rare type of melanoma was discussed.
